While policy debate is often focused on the whole teaching profession, primary and secondary teachers differ in more ways than one. While all countries require teachers to have at least a bachelor degree to enter the profession in primary or lower secondary education, the structure and content of the programmes vary and are less geared towards practice at secondary than primary level. Primary school teachers spend on average 10% more of their working time teaching, though their class size will be slightly smaller. Finally, primary teachers' salaries are less competitive than their lower secondary peers in more than half of the countries. Improving the attractiveness and effectiveness of the teaching profession can only be addressed by recognising these differences and adapting a differentiated policy to address the challenges of each.
